if thats what its called.
The metal one is better, and is what came with the 03/04 trucks. The black plastic one tends to rub against the bottom of the air cleaner assembly until it has a hole in it. The plastic ones also tend to "pop off" under high levels of boost and under high temps. You can order one from Ford as well. Seach the forum for "metal CAC tube". I got one for my 06 a year or two ago. Was about $120 from Tousley Ford.
BTW, you will still see some oil at the intake manifold elbow - even with the metal cold side CAC tube. Mine has just a light amount of oil mist, not the drips that plastic one had. Only a CCV re-route will completely cure this.
